Subject: [PATCH 7/8] arm64: dts: imx8mm-kontron: Fix reset delays for ethernet PHY
Date: Thu, 30 Sep 2021 17:56:30 +0200 [thread overview]
Message-ID: <20210930155633.2745201-8-frieder@fris.de> (raw)
In-Reply-To: <20210930155633.2745201-1-frieder@fris.de>
From: Frieder Schrempf <frieder.schrempf@kontron.de>
According to the datasheet the VSC8531 PHY expects a reset pulse of 100 ns
and a delay of 15 ms after the reset has been deasserted. Set the matching
values in the devicetree.
